Minolta MD Lens to Fujifilm X-Mount Camera Speed Booster ULTRA

About this product

The Metabones Minolta MD Lens to Fujifilm X-Mount Camera Speed Booster ULTRA is a precision optical adapter that enables compatibility between vintage Minolta MD lenses and modern Fujifilm X-Mount cameras. Designed with a 5-element, 4-group optical system using high-refractive-index tantalum-based glass, it enhances image sharpness, reduces distortion, and minimizes vignetting. The adapter reduces the APS-C crop factor from 1.5x to 1.07x, effectively simulating full-frame performance, while increasing the maximum aperture by approximately one stop for improved low-light capability and shallow depth of field. Constructed from precision-machined brass with chromium plating, it ensures a secure, gap-free connection. A detachable tripod foot compatible with Arca Swiss-style heads provides added stability for long exposures. The interior features a matte black finish to suppress internal reflections, and the adapter maintains correct registration distance for CRC and floating-element lenses. It supports infinity focus and is designed for reliable, durable use.
